Abstract (en)
A spark timing control system (10) for an internal combustion engine, comprises a first device (12) for sensing one of engine noise and vibration to generate an output signal corresponding thereto; a second device (20) for generating an output signal when the level of the output signal exceeds a reference value (Vr); and a third device (24) for retarding the spark timing of the engine in response to the output signal of the second device, thereby maintaining engine noise below an allowable limit.
